How is his weight? He's 5 months? You can switch him anytime I think. I just stopped Seger's. Didn't wean him at all.
He will be 6 months on the 16th of July, and he is about 60-65lbs.
He loves to eat, if he's outside and won't come in, all you have to say is "Do you wanna eat?" and he will sprint to the front door haha
